A habit is a regularity in automatic responding to a specific situation. Classical learning psychology explains the emergence of habits by an extended learning history during which the response becomes associated to the situation (learning of stimulus-response associations) as a function of practice ("law of exercise") and/or reinforcement ("law of effect"). In this paper, we propose the "law of recency" as another route to habit acquisition that draws on episodic memory models of automatic response regulation. According to this account, habitual responding results from (a) storing stimulus-response episodes in memory, and (b) retrieving these episodes when encountering the stimulus again. …

“Yo acojo, tú agrupas, ella compensa”: Análisis comparado de la política de integración del alumnado inmigrante en tres Comunidades Autónomas

2015

With the passing of the la Ley Organica de Mejora de la Calidad Educativa [Reform Act of Improvement of Quality in Education] reemerges one of the timeliest educational issues: decision-making in the field of educational policy that takes care of immigrant students. The present moment is an excellent excuse for, from the perspective that Comparative Education offers, the revision of how the collective of immigrant children has been educated through three models of educational management represented by three Autonomous Communities: Valencia, Catalonia and Andalusia. The article focuses on the analysis of the measures taken in these three cases concerning the reception, the welcoming, and the…

La tesis de la postsecularización a la luz de la trayectoria intelectual de Jürgen Habermas

2019

espanolEl presente trabajo reconstruye argumentativamente el sentido de la idea de una ciudadania postsecular desde la perspectiva de Jurgen Habermas, a la luz de su trayectoria y produccion bibliografica. En primer lugar, ofrecemos una periodizacion de su trayectoria intelectual de acuerdo con la atencion prestada y la consideracion que juega la cuestion religiosa en cada una de las fases. Sobre la base de esta periodizacion y vision de conjunto, nos es posible apresar el sentido intrateorico del concepto normativo de postsecularizacion, y mostrar hasta que punto esta tesis constituye un giro en la trayectoria intelectual de Habermas. Despues, exponemos criticamente el sentido de las ultim…

Challenges in the use of Near Infrared Spectroscopy for improving wood quality: A review

2018

Aims of study: Forestry-related companies require quality monitoring methods capable to pass a large number of samples. This review paper is dealing with the utilization of near infrared (NIR) technique for wood analysis.Area of study: We have a global point of view for NIR applications and characterization of different kind of wood species is considered.Material and methods: NIR spectroscopy is a fast, non-destructive technique, applicable to any biological material, demanding little or no sample preparation. NIR spectroscopy and multivariate analysis serve well in laboratories where the conditions are controlled. The main challenges to NIR spectroscopy technique in field conditions are mo…

Culture and odor categorization : agreement between cultures depends upon the odors

2003

This study evaluated the effect of culture on the relationship between psychological dimensions underlying odor perception and odor categorization. In a first experiment, French, Vietnamese and American participants rated several perceptual dimensions of everyday odorants, and sorted these odorants on the basis of their similarity. Results showed that the three groups of participants differed in their perceptual judgments but agreed in categorizing the odors into four consensual groups (floral, sweet, bad, and nature). Three dimensions––pleasantness, edibility, cosmetic acceptability––discriminated these groups in the same way in the three countries. In a second experiment, the participants…

The perception of odor objects in everyday life: a review on the processing of odor mixtures

2014

International audience; Smelling monomolecular odors hardly ever occurs in everyday life, and the daily functioning of the sense of smell relies primarily on the processing of complex mixtures of volatiles that are present in the environment (e.g., emanating from food or conspecifics). Such processing allows for the instantaneous recognition and categorization of smells and also for the discrimination of odors among others to extract relevant information and to adapt efficiently in different contexts. The neurophysiological mechanisms underpinning this highly efficient analysis of complex mixtures of odorants is beginning to be unraveled and support the idea that olfaction, as vision and au…

Does ICT Usage Erode Routine Occupations at the Firm Level?

2019

We present decompositions and regression analyses that evaluate the routinization hypothesis and occupational polarization at the firm level. We establish two important facts. First, the results for the increasing abstract and declining routine occupation shares of total wage bill are consistent with the routinization hypothesis at the firm level. Second, the observed changes coincide with the usage of ICT in firms. This implies that disappearing middle-level (routine) work can be traced to firm-level technological change. Peer reviewed

Revisiting the didactic triangle: from the particular to the general

2012

Published version of an article in the journal: ZDM. Also available from the publisher at: http://www.springerlink.com/content/61p78l089tnx8rn5/ The basic notion of a didactic triangle is explained with historical annotations on its origins and subsequent theorization in the literature. Instances of its application to classroom environments to demonstrate its representational capabilities are presented. Generalizations of the triangle are proposed that integrate the role of technology, the researcher in mathematics teaching developmental research, and mediating complexes in the student–teacher–content interfaces. Further, the use of the didactic triangle as a heuristic device is also discus…

Data from: Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size

2016

Reed bunting (Emberiza schoeniclus) subspecies vary considerably in bill size and shape and seem to be at an early stage of speciation, in which bill might be indirectly causing reproductive isolation. Hence, we evaluated whether bill size, as well as age and sex, are associated with foraging niche in three West European subspecies of reed bunting: the thin-billed schoeniclus, the intermediate-billed lusitanica and the thick-billed witherbyi. Blood sampling was undertaken at three sites in southwest Europe during the winter (when these subspecies co-occur), and stable isotope analyses (carbon and nitrogen) were performed to assess their foraging niches. Stable isotope analyses of potential …

Special Features of the Hippocampal Formation with Respect to Seizure Conditions

1987

The hippocampus has long been known as a region particularly prone to epileptiform discharges (Kandel et al. 1961). Connections and physiology of this archaic cortical structure are relatively well charac-terized and a wealth of information on features favoring exaggerated neuronal activity has emerged in recent years. The lamellar organization of the hippo-campus (Andersen et al. 1971) may be one of these features; it certainly has facilitated their investigation. Tissue slices cut along the lamellae, perpendicular to the axis of the structure, contain a relatively undisturbed chain of neurons which can be rigorously investigated in vitro. The results from such experiments have allowed mod…
